- Marine ecosystems evolve under many interconnected and area-specific pressures. To fulfil society's intensifying and diversifying needs while ensuring ecologically sustainable development, more effective marine spatial planning and broader-scope management of marine resources is necessary. Integrated ecological–economic fisheries models (IEEFMs) of marine systems are needed to evaluate impacts and sustainability of potential management actions and understand, and anticipate ecological, economic and social dynamics at a range of scales from local to national and regional. To make these models most effective, it is important to determine how model characteristics and methods of communicating results influence the model implementation, the nature of the advice that can be provided and the impact on decisions taken by managers. This article presents a global review and comparative evaluation of 35 IEEFMs applied to marine fisheries and marine ecosystem resources to identify the characteristics that determine their usefulness, effectiveness and implementation. The focus is on fully integrated models that allow for feedbacks between ecological and human processes although not all the models reviewed achieve that. Modellers must invest more time to make models user friendly and to participate in management fora where models and model results can be explained and discussed. Such involvement is beneficial to all parties, leading to improvement of models and more effective implementation of advice, but demands substantial resources which must be built into the governance process. It takes time to develop effective processes for using IEEFMs requiring a long-term commitment to integrating multidisciplinary modelling advice into management decision-making.

Internet-based vestibular rehabilitation for older adults with chronic dizziness : A randomised controlled trial in primary care
- 2017
-
Konferensbidrag (refereegranskat)abstract
- Introduction: Vestibular dysfunction occurs in 50% of those over age 60, and with an ageing population the health burden will increase. Vestibular Rehabilitation (VR) has been shown to be effective for dizziness caused by vestibular dysfunction, but it is seldom provided in primary care. The rapid growth in internet access provides a promising vehicle for VR to achieve widespread health impact. We aimed to determine the effectiveness of internet-based VR on chronic dizziness in older adults in primary care.Method: We conducted a single centre randomised controlled trial comparing an internet-based VR intervention with usual primary care. 296 primary care patients aged 50 years and over with current dizziness exacerbated by head movements were recruited from 54 primary care practices from southern England. Patients in the intervention arm accessed an automated internet-based intervention that taught VR exercises and suggested cognitive behavioural management strategies. Dizziness was measured by the Vertigo Symptom Short-Form (VSS-SF) at baseline, 3 and 6 months. The primary outcome was VSS-SF score at 6 months (ISRCTN: 86912968).Results: The VSS-SF was completed by 250 (84%) at 3 months and 230 (78%) at 6 months. Dizziness symptoms were significantly lower in the internet-based VR group compared to usual care at 3 (2.75, 95% CI:1.39, 4.12; p<0.001 and 6 months (2.26, 95% CI: 0.39, 4.12; p=0.018). Dizziness-related disability was also significantly lower in the internet-based VR condition, at 3 (5.33, 95% CI: 1.41, 9.26; p=0.008) and 6 month (5.58 95% CI: 1.19, 10.0; p=0.013).Discussion: Internet-based VR improves dizziness and reduces dizziness-based disability in older primary care patients without requiring structured guidance. The effectiveness without the need for health professional support indicates that this intervention could be made rapidly available to GPs for provision to their patients and wider dissemination in the community.

- In this study, we examine the relationship between risk-taking, impatience and facial masculinity in expert chess players. We combine a large panel data set from high-level chess games with measures of both risk-taking and impatience in chess with facial masculinity, a proxy for testosterone exposure in puberty. We find that male players with high pubertal testosterone exposure are more impatient by playing shorter chess games. For female players, we find that facial masculinity is negatively correlated with risk-taking.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: This article outlines the rationale and development process for an online intervention based on vestibular rehabilitation therapy (VRT). The intervention aims to assist adults aged 50 years and older to self-manage and reduce dizziness symptoms. Method: The intervention was developed according to the person-based approach to digital intervention design focused on accommodating perspectives of target users. A prototype version of the intervention was provided to 18 adults (11 women, 7 men) aged 50 years and older with dizziness. These adults were invited to use the intervention over a 6-week period and, during this time, took part in a think-aloud session. This session sought to understand users' perceptions of how acceptable, engaging, and easy to use they found the online intervention. Results: Users were extremely positive regarding how easy to navigate, visually appealing, and informative they found the intervention. Think-aloud sessions provided valuable data for informing small amendments to further enhance acceptability of the intervention for target users. Conclusions: Informed by these development-phase data, a finalized version of the intervention is now being investigated in a primary care–based randomized controlled trial. Results should provide an understanding of whether VRT can be effectively—especially, cost-effectively—delivered via an online intervention to adults aged 50 years and older.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Dizziness is highly prevalent in older adults and can lead to falls, fear of falling, loss of confidence, anxiety and depression. Vestibular rehabilitation (VR) exercises are effective in reducing dizziness due to vestibular dysfunction, but access to trained therapists is limited. Providing dizzy patients with booklets teaching them how to carry out VR exercises has been shown to be a cost-effective way of managing dizziness in primary care. Internet-based intervention delivery has many advantages over paper-based methods, including the provision of video instructions, automated tailoring and symptom-related feedback. This trial will examine whether an internet-based VR intervention is (1) effective in reducing dizziness and (2) a cost-effective primary care treatment option. Methods/analysis: This will be a single blind, randomised controlled trial carried out in UK primary care. A stand-alone internet-based VR intervention will be compared with routine care in 262 dizzy patients aged 50 years and over. Measures will be taken at baseline, 3 and 6 months. Our primary outcome measure will be the effectiveness of the intervention in reducing dizziness symptoms compared with routine care at 6 months. Cost-effectiveness will be examined along with the effect of the intervention on dizziness-related disability and symptoms of depression and anxiety. Psychological process variables including expectancy, self-efficacy and acceptance will be explored in relation to adherence and symptom reduction. Ethics/dissemination: This trial has undergone ethical scrutiny and been approved by an NHS Research Ethics Committee, Southampton A REC Reference: 13/SC/0119. The findings of this trial will be disseminated to the scientific community through presentations at national and international conferences, and by publishing in peer review journals. Findings will be disseminated to the public through targeted press releases. This trial will provide valuable information on the role of internet interventions in facilitating self-management in older adults.

- PURPOSE: Vestibular rehabilitation is an effective intervention for dizziness due to vestibular dysfunction, but is seldom provided. We aimed to determine the effectiveness of an Internet-based vestibular rehabilitation program for older adults experiencing dizziness in primary care.METHODS: We undertook a single-center, single-blind randomized controlled trial comparing an Internet-based vestibular rehabilitation intervention (Balance Retraining, freely available from https://balance.lifeguidehealth.org) with usual primary care in patients from 54 primary care practices in southern England. Patients aged 50 years and older with current dizziness exacerbated by head movements were enrolled. Those in the intervention group accessed an automated Internet-based program that taught vestibular rehabilitation exercises and suggested cognitive behavioral management strategies. Dizziness was measured by the Vertigo Symptom Scale–Short Form (VSS-SF) at baseline, 3 months, and 6 months. The primary outcome was VSS-SF score at 6 months.RESULTS: A total of 296 patients were randomized in the trial; 66% were female, and the median age was 67 years. The VSS-SF was completed by 250 patients (84%) at 3 months and 230 patients (78%) at 6 months. Compared with the usual care group, the Internet-based vestibular rehabilitation group had less dizziness on the VSS-SF at 3 months (difference, 2.75 points; 95% CI, 1.39–4.12; P <.001) and at 6 months (difference, 2.26 points; 95% CI, 0.39–4.12; P = .02, respectively). Dizziness-related disability was also lower in the Internet-based vestibular rehabilitation group at 3 months (difference, 6.15 points; 95% CI, 2.81–9.49; P <.001) and 6 months (difference, 5.58 points; 95% CI, 1.19–10.0; P = .01).CONCLUSIONS: Internet-based vestibular rehabilitation reduces dizziness and dizziness-related disability in older primary care patients without requiring clinical support. This intervention has potential for wide application in community settings.

Four ways blue foods can help achieve food system ambitions across nations
- 2023

Tidskriftsartikel (refereegranskat)abstract
- Blue foods, sourced in aquatic environments, are important for the economies, livelihoods, nutritional security and cultures of people in many nations. They are often nutrient rich1, generate lower emissions and impacts on land and water than many terrestrial meats2, and contribute to the health3, wellbeing and livelihoods of many rural communities4. The Blue Food Assessment recently evaluated nutritional, environmental, economic and justice dimensions of blue foods globally. Here we integrate these findings and translate them into four policy objectives to help realize the contributions that blue foods can make to national food systems around the world: ensuring supplies of critical nutrients, providing healthy alternatives to terrestrial meat, reducing dietary environmental footprints and safeguarding blue food contributions to nutrition, just economies and livelihoods under a changing climate. To account for how context-specific environmental, socio-economic and cultural aspects affect this contribution, we assess the relevance of each policy objective for individual countries, and examine associated co-benefits and trade-offs at national and international scales. We find that in many African and South American nations, facilitating consumption of culturally relevant blue food, especially among nutritionally vulnerable population segments, could address vitamin B12 and omega-3 deficiencies. Meanwhile, in many global North nations, cardiovascular disease rates and large greenhouse gas footprints from ruminant meat intake could be lowered through moderate consumption of seafood with low environmental impact. The analytical framework we provide also identifies countries with high future risk, for whom climate adaptation of blue food systems will be particularly important. Overall the framework helps decision makers to assess the blue food policy objectives most relevant to their geographies, and to compare and contrast the benefits and trade-offs associated with pursuing these objectives.

Ingår i: Current Opinion in Environmental Sustainability. - 1877-3435 .- 1877-3443. ; 65
-
Tidskriftsartikel (refereegranskat)abstract
- A greater focus on governance is needed to facilitate effective and substantive progress toward sustainability transformations in the aquaculture sector. Concerted governance efforts can help move the sector beyond fragmented technical questions associated with intensification and expansion, social and environmental impacts, and toward system-based approaches that address interconnected sustainability issues. Through a review and expert-elicitation process, we identify five engagement arenas to advance a governance agenda for aquaculture sustainability transformation: (1) setting sustainability transformation goals, (2) cross-sectoral linkages, (3) land–water–sea connectivity, (4) knowledge and innovation, and (5) value chains. We then outline the roles different actors and modes of governance can play in fostering sustainability transformations, and discuss action items for researchers, practitioners, and policymakers to operationalize activities within their engagement arenas.
